I see myself as a neutral. Protect me and mine, let people wipe themselves out (thugs,gangsters,thieves)
Then after a while, help where I can.
Unfortunately, I can't stay hunkered in for a long time. I see myself as security. Every time my dogs bark, I HAVE to look. My dogs do NOT bark at the wind. They bark because something is there. So for my piece of mind, if SHTF and it gets crazy, I'll be the one doing rounds around my and my grammas house. I just couldn't sleep at all knowing that the dogs barked and I ignored it. I'm not machismo at all, and am actually a tad cautious at bumps in the night, but that doesn't stop me from investigating.
But I think it all depends on what scenario and events take place. I don't think anyone can say with any amount of certainty what they will do without a specific scenario. I know if I were in a situation with 100+ people mobbing my street/house, I would do it differently than 10+ people. I would be neutral with 10+ versus 100+. 100+, I'd shoot to kill
